Impulse [1954] [DVD]

Routine British second-feature, typical of its period, although Arthur Kennedy (five times nominated for an Oscar) is a cut above the average imported American lead, and the rest
of the cast isn't bad either

Kennedy has a fling with nightclub singer Constance Smith, who involves him in a crime.

Producers Robert S Baker and Monty Berman began with B-films like
this, moved into Hammer-style horror, and ended up developing several major TV series.
